Hey man,
I've been fucked up pretty badly in my life too. I'm currently putting myself through college completely on my own. I was sexually, emotionally, and physically abused as a child, and my extended family never believed me or gave me any help or support. After getting kicked out of my family for being a gay atheist, I'm still pushing and I refuse to give up. Don't let people have their way with you. If you kill yourself, you're only telling them that they're right. It takes one hell of a person to suffer as you have, and believe me when I say that it's not for nothing.
If I'd have killed myself would I be here to help other people?
You might have been treated poorly, but that's on THOSE people, not YOU. You still have plenty of potential to do good in this world, and the world could fucking use it. Why is it always the assholes sucking up all the resources, but the good people are killing themselves?
Please hang in there, and if you'd like, email me. I can be a phone contact, too if you don't have anyone else you want to talk to.
Be well.
James
